Tiresias Mist is a hit or miss product. Coloidal Silver is essentially distilled water, 2-99.9999 (12-14 guage) silver wires attatched to + and- electrodes and dropped into the water for some time. I have never made it myself, but will start soon. You can make gallons of it with what you bought the tireias mist for. Just my "My 2 cents"
